What it does
Animation Performance is an agent skill from thedaviddias/Front-End-Checklist. Use when reviewing stylesheets, component styles, and responsive behavior related to Use transform and opacity for animations. Check the rendered layout across breakpoints and interaction states before proposing a fix.
Its SKILL.md is about 530 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/rule.md`).
It sits in Frontend & Design, covering CSS and styling and Responsive design. The repository describes itself as: 🗂 The essential checklist for modern web development, for humans and AI agents. The licence is MIT.
When your agent uses it
- Reviewing stylesheets
- Component styles
- Responsive behavior related to Use transform and opacity for animations
Example prompts
- “/animation-performance”
What it can do on your machine
Read from SKILL.md and the folder at commit e8d14d0. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
frontendchecklist.io
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Animation Performance loads about 529 tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 60 tokens; SKILL.md has 219 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Use transform and opacity for animations
Animating layout properties (width, height, top, margin) triggers the full browser rendering pipeline on every frame — style recalculation, layout, paint, and composite. This runs on the main thread and competes with JavaScript. Animating transform and opacity skips layout and paint entirely and runs on a dedicated GPU thread, achieving smooth 60fps even when the main thread is busy.
Quick Reference
- Only transform and opacity can be composited on the GPU without triggering layout
- Use will-change: transform sparingly to promote an element to its own compositor layer
- Prefer CSS transitions and animations over JavaScript animation libraries for simple effects
- Respect prefers-reduced-motion to disable animations for users who need it
Check
Find CSS animations or transitions in this file that animate layout-triggering properties like top, left, width, height, or margin. Flag them for optimization.
Fix
Convert layout-triggering animations to use transform equivalents: position changes to translate(), size changes to scale().
Explain
Explain the browser rendering pipeline, why transform and opacity are performant for animation, and how the GPU compositor works.
Code Review
Review stylesheets, component styles, and responsive states related to Use transform and opacity for animations. Flag exact selectors, declarations, or breakpoints that violate the rule in the rendered UI.
